Please refer to FIG. 2. FIG. 2 is a structure diagram of one touch screen provided by the embodiment of the present invention. The touch screen 100 of this embodiment comprises m scan blocks 110.

Each scan block 110 comprises a GOA (Gate Driver On Array) stage transfer circuit 113, n scan lines 115 and at least one TP (touch panel) scan module 117. Please refer to FIG. 3 together. A first input end of the GOA stage transfer circuit 113 is employed for inputting a STV signal, and a second input end of the GOA stage transfer circuit 113 is employed for inputting a CK (clock) signal, and the GOA stage transfer circuit 113 comprises n GOA units 1131 which are cascade connected, and an ith GOA unit 1131 in the GOA stage transfer circuit 113 is employed to charge an ith scan line 115, and an nth scan line 115 is coupled to the at least one TP scan module 117. The CK signals in the different scan blocks 110 can be solo, or can be multiplexed.

As scanning, a first STV signal in inputted to the GOA stage transfer circuit 113 in the first scan block 110 to start scanning the first scan block 110. In cooperation of the CK signal, the GOA stage transfer circuit 113 in the first scan block 110 controls and accomplishes charging the first scan line 115 by the first GOA unit 1131 to charging the nth scan line 1131 by the nth GOA unit 115 for accomplishing the scan to the image signal of the first scan block 110. After the nth GOA unit 1131 in the first scan block 110 charged the nth scan line 115, the signal outputted by the nth scan line 115 drives the TP scan module 117 to work for accomplishing the scan to the touch signal of the first scan block 110. After the scan to the first scan block 110 is accomplished, the second STV signal is inputted to the GOA stage transfer circuit 113 in the second scan block 110 to start scanning the second scan block 110.

Please refer to FIG. 4 together. By employing the aforesaid method, the touch screen 100 can be divided into a plurality of scan blocks 110 to be sequentially scanned. Meanwhile, there is the scanning period in the scanning period of each scan block 110. Thus, in the scanning period of one frame, there can be scanning periods of a plurality of independent touch signals. For instance, the time period of one frame is 16 milliseconds, and the touch screen 100 is divided into four scan blocks 110 for scanning. The scanning period of each scan block 110 is 4 milliseconds. In the scanning period of each scan block 110, the previous 3 milliseconds is the scanning period of the display signal, and the latter 1 millisecond is the scanning period of the touch signal. Thus in the period of one frame, there are scanning periods of 4 independent touch signals respectively. Because in the scanning period of one frame, there are scanning periods of a plurality of independent touch signals, even the capacitance signal measured at the initial moment of the scanning period of one touch signal is influenced by the environment, and no influence is caused to the touch signal of the scanning period of other touch signals.

It is understandable that the scanning period of each scan block 110 can be set to be the same, or can be set to be different. Similarly, the scanning periods of the image signals in different scan blocks 110 can be set to be the same, or can be set to be different. The scanning periods of the touch signals in different scan blocks 110 can be set to be the same, or can be set to be different.

In other embodiment, the structure of the touch screen 100 is unchanged, and meanwhile, the size of each scan block 110 is the same. However as scanning, at the same moment, the STV signal is respectively inputted to m GOA stage transfer circuits 113 to start scanning m scan blocks at the same time. Namely, at the same moment, the first STV signal is inputted to the GOA stage transfer circuits 113 in the first scan block 110, and the second STV signal is inputted to the GOA stage transfer circuits 113 in the second scan block 110, and . . . , and the mth STV signal is inputted to the GOA stage transfer circuits 113 in the mth scan block 110 to start scanning the first to the mth scan blocks 110. In cooperation of the CK signal, the GOA stage transfer circuits 113 in the respective scan blocks 110 control and accomplish charging the first scan lines 115 by the first GOA unit 1131 to charging the nth scan line 115 by the nth GOA unit 1131 for accomplishing the scan to the image signals of the respective scan blocks 110 at the same time. After the respective scan blocks 110 accomplish the scan to the image signals at the same time, the nth scan lines 115 of the respective scan blocks 110 output signals at the same time to drive the TP scan modules 117 to work.

Please refer to FIG. 5 together. By employing the aforesaid method, the touch screen 100 can be divided into a plurality of scan blocks 110 to be scanned at the same time. Therefore, the period of scanning the touch screen 100 is enormously decreased, and the period of scanning the touch signal of the touch screen is enormously decreased, too. For instance, the touch screen 100 is divided into 4 scan blocks 110 to be scanned at the same time. Previously, it takes 16 milliseconds to accomplish scanning the touch screen 100, wherein 12 milliseconds is the scanning period of the image signal of the touch screen 100, and 4 milliseconds is the scanning period of the touch signal of the touch screen 100. After dividing the scan blocks 110 to be scanned at the same time, it only takes 4 milliseconds to accomplish scanning the touch screen 100, wherein 3 milliseconds is the scanning period of the image signal of the touch screen 100, and 1 millisecond is the scanning period of the touch signal of the touch screen 100. Therefore, the period of scanning the touch screen 100 is enormously decreased, and the period of scanning the touch signal of the touch screen is enormously decreased, too. Therefore, in the same period, the method of dividing the touch screen 100 into a plurality of scan blocks 110 to be scanned at the same time can raise the scanning number of the touch signal. Even the capacitance signal measured at the initial moment of the scanning period of one touch signal is influenced by the environment, and no influence is caused to the scan of other touch signals.

After the nth GOA unit in the first scan block 110 charged the nth scan line 215, the second CK signal is inputted to the TP scan module 217 in the first scan block 210 to start the scan to the touch signal of the first scan block 210 by the TP scan module 217 in the first scan block 210. After the scan to the first scan block 210 is accomplished, the second STV signal is inputted to the GOA stage transfer circuit 213 in the second scan block 210 to start scanning the second scan block 210. In cooperation of the first CK signal, the GOA stage transfer circuit 213 in the second scan block 210 controls and sequentially accomplishes charging the first scan line 215 by the first GOA unit to charging the nth scan line 215 by the nth GOA unit for accomplishing the scan to the image signal of the second scan block 210. After the nth GOA unit in the second scan block 110 charged the nth scan line 215, the second CK signal is inputted to the TP scan module 217 in the second scan block 210 to start the scan to the touch signal of the second scan block 210 by the TP scan module 217 in the second scan block 210, and so on until the scan to the mth scan block is accomplished.

In other embodiment, the structure of the touch screen 200 is unchanged, and meanwhile, the size of each scan block 210 is the same. However as scanning, at the same moment, the STV signal is respectively inputted to m GOA stage transfer circuits 213 to start scanning m scan blocks at the same time.
